You don't have the reload icon at the far right of the address bar? You can also press the "cmd" key and the R key at the same time to force a page reload in Safari. The cmd key has a square with loops on all four corners, at least that's how I describe it...

I don't have a apple keyboard kept the Windows 10 keyboard. All Apple stuff is so high.

You should be able to use the "Windows" key in place of the Mac cmd or command key. Apple describes this key as a four leaf clover, but to me it's a bit of stretch unless they are more realistic on later Mac keyboards. Anyway, here are the main equivalents to unique Mac keys on a Windows keyboard:

Mac                    Windows

Control               Ctrl
Option                Alt
Command           Windows Key
Delete                 Backspace
Return                Enter

This should help you out a bit... and yes, almost anything Apple tends to be pricey. There are a few aftermarket options, like a USB Mac keyboard at Walmart for around $15.
